Forget the old rule that outdoor pools must live at 7.4 pH. We dig into why cyanuric acid, not pH, is the dominant force behind chlorine strength in the sun, and how reframing your strategy around the FC-to-CYA ratio can reduce algae, cut costs, and protect your surfaces. With insights from industry committee work and modeling, we explain why a 20:1 CYA-to-free chlorine ceiling matters, why 30–50 ppm CYA often hits the sweet spot, and how to choose targets that keep chlorine working without d...
